Ubuntu: Usable Linux

We use 802.1x certificates to authenticate ourselves on the wireless network at work. I couldn’t configure my system to use a (valid) 802.1x certificate using the applet that is installed by default after installing Ubuntu 9.10 on my Dell Latitude D600. After trying various things and reading a lot of posts on this topic, I decided to uninstall NetworkManager and install wicd instead. That got it working within a few minutes.
